Egg Vitrification

If you want to delay motherhood, at WeFIV we recommend Egg Vitrification, so you can fulfill your dream of becoming a mother whenever you wish.

What is Egg Vitrification?

Its main advantage is that it postpones a woman’s reproductive capacity, giving her the chance to become a mother in the future without experiencing a decline in her ability to conceive. This technique makes it possible to preserve the quality and morphology of the eggs while they are frozen, resulting in a higher success rate of treatments than if the eggs had not been vitrified earlier.

Who benefits from Egg Vitrification?

  • Women who, for various social reasons, wish to delay motherhood.
  • Oncological and non-oncological patients who will receive gonadotoxic treatments.
  • Those who have undergone repeated surgeries on the ovary.
  • Patients undergoing embryo transfer in a cycle different from follicular stimulation.
  • Women with a low response for accumulating eggs or having a sufficient amount if undergoing a Preimplantation Genetic Testing (PGT) cycle.

At WeFIV, we specialize in the use of of the Cryotop technique, the most innovative and recommended due to its high success rates: 97% of vitrified eggs do not suffer damage (obtained from patients under 35 years of age), the pregnancy rate is 65%, and the implantation success rate is 40%.

Benefits and recommendations of Egg Vitrification

  • This technique preserves a woman’s current egg quality and genetic condition for future use, avoiding complications from aging.
  • For women undergoing cancer treatment, with the consent of their oncologist, ovarian stimulation will be performed so that once the cancer treatment is completed and the woman has recovered, she can proceed with the IVF process.
  • It is a simple and quick treatment that has a high impact on the success rate of future assisted reproduction treatments. This is because the quality of the eggs is preserved at the time of cryopreservation. 
  • Thanks to this technique, an older woman can undergo assisted fertility treatment to achieve pregnancy with her own eggs, vitrified years earlier, without the need for egg donation.
  • It can also be used for women with various pathologies that hinder the proper functioning of their ovaries. In this way, when the required number of eggs is not obtained, more than one stimulation can be performed to obtain a greater number of embryos and select the one with the best morphological quality and chances of successful implantation in the mother’s uterus.
  • It is also most suitable in cases where the couple cannot provide a semen sample on the same day as the ovarian puncture for any reason.
  • Women who for different social reasons wish to postpone motherhood.

  • To oncological and non-oncological patients who are going to receive gonadotoxic treatments.

  • To those who have received repeated ovarian surgeries
    To patients who undergo embryo transfer in a cycle different from that of follicular stimulation.

  • To women with a low response to accumulate oocytes or to have a sufficient quantity if a Preimplantation Genetic Testing (PGT) cycle is to be performed.

    At WeFIV we specialize in the incorporation of the Cryotop technique, the most innovative and recommended given its high percentages of effectiveness: 97% of vitrified oocytes do not suffer damage (obtained from patients under 35 years of age), the pregnancy rate is 65% and 40% successful implementation.

  • This technique delays motherhood to an age when your genetic condition and the quality of the eggs have not yet been affected by age.
  • For women who must receive oncological therapy, with the consent of their oncologist, ovarian stimulation will be performed so that once the cancer treatment is finished and they have recovered, they can carry out the IVF process.
  • It is a simple and quick treatment that has a high impact on the success rate of assisted reproduction treatment performed in the future. This is because the oocyte quality from the moment cryopreservation was performed is preserved.
  • Thanks to this technique, an elderly woman can undergo assisted fertility treatment to achieve pregnancy with her own eggs, vitrified years before, without the need to resort to egg donation.
  • It can also be used for women with different pathologies that make it difficult for their ovaries to function properly. Thus, when the necessary number of oocytes is not obtained, more than one stimulation can be performed to obtain a greater number of embryos and select the one with the best morphological quality and probability of successful implantation in the mother’s uterus.
    It is also the most appropriate in those cases in which the couple cannot provide the semen sample on the same day as the ovarian puncture for any reason.
  • Oocyte vitrification consists of carrying out a solidification process in which the oocytes are treated with cryoprotective substances and are immersed in liquid nitrogen at a temperature of -196 ºC.

  • At WeFIV we have a group of professionals specialized in reproductive medicine who have the latest technology at their disposal to provide quality care to all our patients. Precisely, for oocyte vitrification, we incorporate the Cryotop technique, the most innovative and recommended worldwide for this type of treatment as it is considered the most effective method in oocyte cryopreservation.

  • The procedure is similar to In Vitro Fertilization, it begins with ovarian stimulation with hormones so that the ovaries develop multiple follicles at the same time, when they are of the appropriate size the specialist proceeds with follicular puncture to obtain the eggs. Finally, the Cryotop technique is continued for cryopreservation in liquid nitrogen.

  • The reasons and indications why oocytes are vitrified are very diverse but have as a common denominator the fact that the woman desires and decides to postpone her motherhood. The oocytes can be kept cryopreserved for the period determined by the patient; there is no stipulated time limitation.

What is the procedure?

Egg vitrification involves a solidification process in which the eggs are treated with cryoprotectant substances and immersed in liquid nitrogen at a temperature of -196 ºC.

At WeFIV we have a group of professionals specialized in reproductive medicine who have access to the latest technology available to provide quality care to all our patients. We use the Cryotop technology, the most innovative and recommended worldwide, as it is the most efficient approach for egg cryopreservation.

The procedure is similar to In Vitro Fertilization, it begins with ovarian stimulation with hormones so that the ovaries develop multiple follicles at the same time, when they are of the appropriate size the specialist proceeds with follicular puncture to obtain the eggs. Finally, the use of Cryotop continues for cryopreservation in liquid nitrogen.

Although the need for vitrifying eggs differs, the common factor is that the woman wants to delay becoming a mother. The eggs can be cryopreserved for as long as the patient wishes; there is no stipulated time limit.

What is the procedure for oncological patients?

At WeFIV, we offer the egg vitrification process for women diagnosed with cancer who want to become mothers once they have recovered, maintaining the reproductive prognosis at that time. This is mainly because infertility can be caused by cancer treatments such as:

  • Chemotherapy: affects all cells in the body, destroying tumor cells but also dividing cells, including eggs. One of the most likely side effects is a reduction in the number of eggs, although risks vary depending on the treatment.
  • Radiotherapy: there is a high risk that radiation to both the uterus and ovaries will cause permanent infertility or sterility. In some cases, menstruation takes months or even years to return after treatment is completed. In fact, even if the woman recovers her menstrual cycle, fertility is reduced.
  • Surgery: some women with cancer must undergo surgery to remove the tumor, either in the reproductive organs (ovaries, fallopian tubes, uterus) or near them. In both cases, the procedure can significantly affect the woman’s fertility.

At WeFIV, we consider it essential that every young patient diagnosed with cancer has access to information about each cancer treatment, how it may affect their fertility, and the possibilities available for preserving it. We believe they should have the option of becoming mothers once they have recovered from their treatment whenever possible.

Various factors are considered when recommending egg vitrification for a patient with cancer, such as age, ovarian function, follicular reserve, time available to perform the technique before starting chemotherapy, and approval from the patient’s oncologist. The reproductive prognosis will vary depending on the number of eggs that can be vitrified and the age at which the procedure is performed. Although pregnancy cannot be guaranteed, we can offer these patients the possibility and hope of trying through IVF.
